The statement that gets the connection is as follows

public static Connection getconnection () {
String className = Smbmsproperties.getinstance (). GetValue ("Jdbc.class");
String user = Smbmsproperties.getinstance (). GetValue ("Jdbc.user");
String password= smbmsproperties.getinstance (). GetValue ("Jdbc.password");
String URL = smbmsproperties.getinstance (). GetValue ("Jdbc.url");
Connection Connection=null;
try {
Class.forName (className);//Load Driver
Connection=drivermanager.getconnection (URL, user, password);//Get Database connection
} catch (Exception e) {
E.printstacktrace ();
}
return connection;
}

I came up with this problem because I started sharing wifi on my computer, which caused my own error.

It should be a network conflict, do not turn on sharing wifi after reboot OK
